GROUP CHECK
Pro Check
The “Pro Check” identifies transmitters which are outside
of specification. We especially recommend performing the Pro
Check on older 1- and 2- antennae devices and in general
for devices which have not been tested by the manufacturer
for a prolonged period of time. The Pro Check
function must be turned on in the “Pro Settings” (see chapter
„Pro Settings”).
The pro check verifies the transmit frequency (Freq: deviation
+/- in Hz from 457’000 Hz), the period lengths (Period:
duration of the period in milliseconds ms) as well as the pulse
duration (Pulse: duration of the signal in milliseconds ms). The
device which needs to be tested is set to SEND mode, the
distance between the participants must be increased to 5m for
the pro check. The group leader activates group check on his
device and scrolls down with the side key to the function pro
check. Wait until the device has performed the test and the test
results are shown.
In case the “Pro Check” discovers problems, the device
must not be used. Have the device checked by the manu-
facturer (see chapter «Maintenance and Repair»).
